回答1:

You can use the change event on the autocomplete widget to achieve this. http://api.jqueryui.com/autocomplete/#event-change

For example:

function AutoComplete() {
  //Autocomplete added to the textbox.
  $('.userSearch').autocomplete({
      source: function (request, response) {
         // your ajax code
      },
      minLength: 1,
      change: function (event, ui) { SaveData(); }
  });
}

回答2:

$('.userSearch').trigger('change');

That will trigger "change" event

回答3:

$('#1').autocomplete({
    select: function(event, ui) {
        "use strict";
        alert('select event called');
       },
    source: ["ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++", "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran", "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl", "PHP", "Python", "Ruby", "Scala", "Scheme"],

    minLength: 1,
    change: function(event, ui) {
        if (ui.item) {
            alert("ui.item.value: " + ui.item.value);
        } else {
            alert("ui.item.value is null");
        }
        console.log("this.value: " + this.value);
    }
});

This will can perform both select and change event for autocomplete.

KDRVN is correct.

$( ".selector" ).autocomplete({
  select: function( event, ui ) {}
});

as in

$( "#models" ).autocomplete({source: models,  select: function( event, ui ) {alert('flippy');} });

Not any of these:

    $('#models').on('select', function() { alert('waawoo'); });
    $('#models').on('change', function() { alert('feefaa'); });
 onchange="updateModels(this)"
